Title: Electronic still camera
Inventor: SAITOU EIICHI
IPC: G03B7/16
Filed: 1984-04-05
Abstract: PURPOSE:To record video signals of proper level by controlling the error of exposure and controlling the degree of abnormality of recording at the time of stroboscopic photographing. CONSTITUTION:Simultaneously with starting of releasing a shutter, output of a photodetecting element 6 is integrated by an integration controlling signal (c), and integration output (d) is compared with a specified value V1 for becoming proper exposure by a comparator circuit 8, and when the output become V1, a light emission stop signal is sent to a stroboscope. Simultaneously with starting of a rear curtain, the output (d) is held by a sample and hold (S/H) circuit 15. In this case, due to delay etc. of the circuit, for instance, when exposure is deviated to overexposure side, the difference of hold voltage V2 of the circuit 15 from the above-mentioned V1 is taken by an exposure error voltage generating circuit 16. The gain of a gain controlling circuit 17 changes according to the value of V2-V1, and the video signals of appropritate level are sent always to a recording circuit 10.

Abstract: PURPOSE: To form the bump electrode with Sn and Sn-Pb which is easily etched through the electroplating method.  
     CONSTITUTION: Al wiring 2 formed on Si substrate 1 via SiO 2 6 is covered with SiO 2 7, and the opening 8 is drilled to form composite film 3 of Cu and Ti. Then resist mask 4 is coated to give the electroplating to low-fusing point metal layer 5 of 5%-Sn and 95%-Pb by about 50μm, and then the gold film of about 1μm is coated to be sintered at about 200°C. Thus, Au-Sn-Pb alloy layer 9 is formed on layer 5. Mask 4 is then removed with exposed film 3 removed by etching, and Au is dissolved completely into Sn-Pb by reflowing. As a result, vamp electrode 10 of a uniform composition can be obtained. In this method, the bump electrode can be formed in a high accuracy and through a simple process.

IPC: B21D37/00
Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To obtain an identification data of a pallet having little trouble and recognition error by detecting the detecting surface of a dog arranged on the side surface of the die with a detecting switch. SOLUTION: The identification plate 3 is arranged on the side surface of the die 2 carried in a press machine 1. In the identification plate 3, the dogs 3A having wide projecting part and narrow recessed part and the dogs 3B having narrow projecting part and wide recessed part corresponding to the identification data are arranged. During shifting the die 2, a dog detecting switch 4 detects the first projecting part in the dog and obtains a pulse and then, 1 of ON-signal of the detecting signal is stored. Even if the dog is run into the recessed part and the detecting signal becomes 0 of OFF-signal, the storing work to this signal is continued. It is judged that the dog detecting switch 4 is ON-damage when the die 2 is ON at the waiting position A or the setting position B.  It id judged that the dog switch is OFF-damage in the case of showing the OFF signal as it is even if the die 2 is shifted to the setting position B.

Title: Magnetostatic wave filter bank
Inventor: ASAO HIDEKI
IPC: G01R23/165
Filed: 1986-03-25
Abstract: PURPOSE:To obtain a mangetostatic wave filter bank operated at a minimized magnetic field by providing a magnetic circuit impressing a DC magnetic field perpendicular in the lengthwise direction of the strip of a strip shaped YIG thin film waveguide path and in parallel with the thin film face. CONSTITUTION:The magnetic field circuit 22 is constituted between permanent magnet plates 19 and 20 so as to apply the DC magnetic field perpendicular in the direction of the strip of the 1st-3rd strip YIG thin film conductor guide paths 1-3 and in parallel with the thin film face. Since the area of opposed magnetic poles of the two permanent magnet plates 19, 20 differs from each other, the DC magnetic field of the gap is ununiformized. Since the direction of the impressed DC magnetic field is within the YIG thin film face and the thickness of the strip YIG thin film is several tens of microns, which is mush smaller than the width and length, the effect of the anti-magnetic field is neglected and the strength of the DC magnetic field in the operation at a required frequency band is very small.

Title: Method and apparatus for producing laminated metal plate
Inventor: FUNAKI MICHIHIRO
IPC: B32B37/00
Filed: 1993-03-05
Abstract: PURPOSE:To obtain a laminated metal plate excellent in close adhesiveness, corrosion resistance and appearance and enhanced in yield by making the width of the thermoplastic resin film flowing down between a press bonding roll and a metal plate larger than that of the metal plate to coat the metal plate with the resin film over the entire width thereof at the central part of the resin film and providing holes to the surface of a winding roll at the coating part of the resin to peel the resin film from the winding roll. CONSTITUTION:By preheating a metal substrate before coating the same with a molten resin, the flowability of the resin is enhanced and the close adhesiveness of the resin to the metal substrate is enhanced. When the metal substrate is not preheated, the close adhesiveness to the resin is not sufficient and the corrosion resistance of the metal substrate becomes inferior. Next, the width Wp of a thermoplastic resin 3 is made larger than the width WM of the metal substrate 1 on the surface of a winding roll 4 around which the preheated metal substrate 1 is wound to pass and holes 10 opened in the axial direction of the part to be coated with respect to the thermoplastic resin covering the openings formed to the surface of the winding roll 4 are provided to the winding roll 4. Air can be also injected from the holes in the rearward part from the pressure contact position of a press bonding roll 5. Even in a method injecting no air, a coating area is reduced by the opening area and the release of an overcoat resin becomes easy.

Abstract: PURPOSE:To perform satisfactory recording and reproduction with less time base fluctuation by forming a band-shaped projecting face in the circumferential direction on an area including the projecting position of a magnetic head on the outer peripheral surface of a rotary drum. CONSTITUTION:A magnetic head 15 is attached to a position near to a fixed drum 11 of a rotary drum 12 so that the leading end part of the head is protruded from a head projection part 14, which is formed on the outer peripheral surface 13 of the rotary drum 12 by a prescribed extent. A band-shaped projecting face 16 is formed on the area, which includes the projecting position of the head 15 on the outer peripheral surface 13 of the rotary drum 12, in the circumferential direction of the rotary drum 12. Consequently, the tape drawn to the rotary drum side by the pressure spike due to the separation of the head 15 on the rotary drum 12 from the tape is received by this projecting face. Thus, the oscillation due to collision between the tape and the head 15 is relaxed to perform satisfactory recording and reproduction where the time base fluctuation caused by the oscillation of the tape is reduced.
